I have been using DDG as my main search engine for a few years now. I occasionally try out other search engines, but I haven't been to Bing (directly) or Google for many months at least. DDG is "good enough" for me. If I can't find a reasonable result to my query, I work on modifying my search terms or just give up.

Having said that, my main concern is that someday in the future DDG will be sold to some less ethical company and I'll have to abandon it (having to start the search for a new search engine of choice all over again).
